((21. 114-435)The present invention relates to new and useful improvements in shipsfor use particularly in time of war, and has for its primary object toprovide a vessel of this character comprising unique means for carryingand expeditiously and safely launching a plurality of small but swiftand powerful protective or life boats.

Another very important object of the invention is to provide a ship ofthe aforementioned character which embodies novel means for recoveringthe boats. 4

Other objects of the invention are to provide a ship of theaforementioned character which will.

be comparatively simple in construction, highly eflicient in operation,seaworthy, and which may be produced at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of thefollowingspecification, taken in connection with the accompanying drawingswherein like characters of refer-' ence designate corresponding partsthroughout the several views, and wherein:

Figure l is a view in side elevation of a ship constructed in accordancewith the present invention.

Figure 2 is a fragmentary view in horizontal section, takensubstantially on the line 2-2 of Figure 1.

Figure .3 is a fragmentary view in vertical 1ongitudinal section, takensubstantially on the line 3-3 of Figure 2.

Figure 4 is a cross sectional view, taken substantially on the line 4-4of Figure 3.

Figure 5 is a cross sectional view through the crane.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a shipJincluding a hull 2. Of course, the hull 2 may be of any suitabledimensions and material. The sides 01 the hull 2 are provided, in thebow portion of said hull, with series of openings 3.

Within the hull 2, adjacent the openings 3, is a substantiallyanticlinal deck 4. Fuel tanks 5 are provided below the deck 4. Below thefuel tanks 5, ballast tanks or chambers Gare provided.

Standards I rise from the axis portion of the deck .4. Longitudinalshafts 8 are fixed on. the standards I. Transversely extending platforms9 are mounted, at an intermediate point, for rock-' ing movement in avertical plane on the shafts 8. Toward this end, the platforms 9 includedepending bearings III which are journaled on the shafts on their sternsa plurality of depth bombs, as at 8. Opposed, coaxial disks II are fixedon the shafts 8 and the plaforms 9. The pairs of disks ll have formedtherein openings l2 for registry with each other, Pins l3 areinsertibleselectively in the registering openings I2 for-releasably' securing theplatforms 9 against rocking or swinging movement on theshafts 8.

The platforms 9 are adapted to support and launch boats l4. Toward thisend, the platforms 9 further include rollers l5 and, opposed guides 30adjacent the ends of said rollers. Cradles ,3l,

for the boats 14, travel on the rollers IS in the guides 30. Chains l6releasably connect the boats M to the platforms 9. Platform H n the deck4 facilitate getting into and out of the boats l4; I

Mounted longitudinally in the side portions of the hull 2, above theboats 54 onthe platforms 9, is a pair of tracks 68 in the form of Ibeams. A transverse crane I9 is operable on the tracks Hi. The crane I9comprises an inverted channel iron 20 having fixed on its ends carriages2|, said carriages including rollers 22 which travel on the tracks l8.Fixed on the side portions of the channel, iron 20 and dependingtherefrom in parallelism therewith is a pair of opposed channel guidemembers 23 having rollers 24 mounted in their lower portions. A boom 25in the form of an I beam is operable on the rollers 24 between theguides 23. A carriage 26 is operable 0n the boom 25. Coacting stops 21on the channel iron 20 and the boom 25 limit the travel of the latter.Stops 28 for a similar purpose are provided on the boom 25 for thecarriage 26. Rollers 32 on the boom 25, outwardly of the stops 21thereon, travel beneath the channel member 20 for preventing said boomfrom binding thereon.

It is thought that the operation of the invention will be readilyapparent from a consideration of the'foregoing. Briefly, to launch theboats M, the chains l6 are released and the pins l3 are withdrawn. Thus,the platforms may be rocked on the shafts 8 to an inclined position forlaunching the boats through either of the openings 3, the platforms 3|traveling by gravity on the rollers l5. Stops 33 on the guides 30 bringthe cradles 3| to a sudden stop and the boats I'4 slide by momentum andgravity from said cradles into the water.

In the embodiment shown, the boats l4 are ofthe protective or combattype. These boats are of any suitable construction, and they may carry29. These boats mayalso include any suitable arrangement of airchanrbers for righting them jected laterally throughthe desired openin'gI over the water, as suggested in broken lines in Figure 4 of thedrawings. The boats ll arethen lifted out of the water by meansincluding a suitable block and tackle arrangement suspendedfrom. thecarriage 2|. The crane I! may be manually or power operated. If desired,the openings 3 maybe closed in any suitable manner. The construction andarrangement, it will be observed, is such that the boats may be launchedand recovered; on either side of the hull 2.

It is believed that the many advantages of a ship constructed inaccordance with the present invention will be readily understood, andalthough a preferred embodiment of the vessel is as illustrated anddescribed, it is to be understood that changes inthe details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.

assay/s What is claimed is:

A ship comprising a hull having transversely aligned openings in itssides, a substantially anticlinal deck in the hull between the openings,standards rising from the longitudinal axis of the deck, a shaft fixedon the standards and paralleling said longitudinal axis of the deck, aplatform pivotally mounted, at an intermediate point, for rockingmovement in opposite directions and in a vertical plane on theshaft,said platform including rollers and a pair of guides, a cradle, forsupporting a boat and for launching said boat through either of theopenings, operable on the rollers in the guides, and means forreleasably.

securing the platform against rocking movement on the shaft, said meansincluding opposed, coaxial disks flxed on the platform and the shaft.said disks having openings therein for registry with each other, and apin insertible in the registering openings.
